ok so i think i'm in trouble
decided to change spark plugs as 50k miles
got the bosch platinum +2 realized that cars's not running correctly...i think the spark plug is firing intermittedly so the plugs are not gap-able but it prolly isnt the problem compared to the fact that i could have a) overtightened and stripped the aluminum head (unlikely but possible) b) did not put the "box" onto the plug tight enough c) broke the plug wire and suggestions of what i should do to diagnose this problem (hopefully the cheapest way) help!!! thanks igor |
Bosch spark plugs are junk. I would replace them with OEM NGK plugs. See if that helps.

Try to put the stock spark plugs back in and see if you still have the problem.

I'm not a mechanic, or that knowledgeable with the problem you're having.
But one time when I decided to put the Bosch Platinums on my 89 Acura Integra, the car never ran right. After a few weeks one of the sparkplugs flew up hitting the hood leaving a little dent. When that happened, I changed them out, with the basic NGK's (I wanted the higher end ones, but the auto parts place was out of them). Never had a problem again. I thought it might have been the gaping, but I checked it with the gap measuring tool (I think they already com pre-gapped), then I thought they might not have been on too tight, but if anything I overtightened. Maybe our Japanese cars don't like German parts? lol :confused: I would try the NGK's and see if you still get the same problem. I'm sure, others will have better advice. |
If Honda's are similar enough to Toyotas...please do not use Bosche plugs on them.
Bosche plugs have been nothing but trouble for Toyotas and it boggles my mind why people would use them over OEM or even OEM brands such as Denso/NGK. For some reason the Bosch plugs just cause misfiring issues regardless of gap etc. That's not to say they make an inferior product or products...but history has told us that they do not work well with japanese vehicles. They work great in Euros (as they should...) |
unfortunately...i had put the oem plugs back in and the problem still exists
now either im an idiot and cannot put the "box" (sorry for callign it that..i dont know the exact name) onto the plug correctly or i screwed up the plug wire and have to dive into taht bs when i get home i'm going to make sure the boxes are on the plugs correctly and if that fails im going to have to get plug wire.... how hard of an install is that? and suggestions? thank you for replies igor |
Can't help you with your problem, but the "box" is the coilpack if I understand what you're talking about.

First off, I'd say check and make sure all your plugs and wires are connected no only PROPERLY but in the CORRECT ORDER.
I switched plugs 2 and 3's wires once on my old explorer and it idled/ran like crap. It's an easy, albeit silly, mistake - I'm sure many people have done it but few will admit to it. If that doesn't help, I'd get away from the Bosch plugs like already mentioned and check the torque on each plug too, to make sure none are loose. I use loctite blue on my plugs/cars whenever I change them out as well, for extra insurance. If you want to upgrade plugs, you should upgrade wires too, IMO. I've yet to do it on my Fit but when I do, they go hand in hand. |
2 reason...1) Honda dont run on Bosch, they use NGK or Denso. 2) you dont have to replace the plugs or do a tune up until 100,000 miles...that the problem. :)

bosch...
anyways.. my idle was being screwy so i decided to use the plugs my friend had which he never used which is why i changed them i think im gonna attribute this strange behavior of the car to a bad batch of gasoline...i put some octane booster and filled up with 89 and i THINK it's running fine.... praying it is rather... and yes...honda's dont run on bush...lol but the CAN run on BOSCH if you want them to...bosch is a decent company but it COULD have to do with the fact that its not SUPPOSED to be run on jap cars... anyways im gonna go do some spirited driving in the local canyon thanks for the responses and help igor |
soorrryyy.... bush...lol. i was thinking of the president that his leving sooooonnn...jaja :rotfl: jk
|
lol
i was gonna say honda's would run on cheney if anything fat ugly but surprisingly deadly when pushed sounded funny-er in my head and now my car is gonna stop working completely cuz i called it fat and ugly anywas peace |
hondas are not meant to run anything BUT ngk plugs. so stay with oem or aftermarket ngk plugs. if u didnt tighten the spark plug(s) correctly u may melt the coil packs.. just double check ur work. i wouldnt do spirited driving til its running right!

Pretty much all spark plugs will come with a crush washer built in nowdays, if you install them correctly you wont have any issues.

How exactly do you plan on upgrading the spark plug wires when there are none? This is a coil-on-plug operation. No wires. No need to upgrade, the stock coils will support far more power than you're making right now. As stated before: Bosch plugs are trash. All of them. Use NGK's and only NGK's. And as stated before, sounds to me like you connected the wires wrong and the coilpacks are firing in the wrong order. |

You realize this was caused by own stupidity (sorry to put it that way but its true) and your very lucky you didn't destroy the threads in the head. A spark plug shooting out is your fault, not the fault of a bad product.
It couldn't have been me switching the wires, because I only do 1 wire/plug at a time. Which is why I still think the Acura was rejecting the Bosch Platinums, kinda like bad organ transplant. oh well NGK ftw!!!!! :D |
the only way your gonna shoot a plug out is from not tightening them correctly.

lol okay
TO the coilpack there ARE wires which you can damage thats the first friggin thing second friggin thing is you CANNOT put them in the wrong order cuz the wires are just that short so before you accuse me blatently ;) of being stupid enough to not put them in the right order go check it out! :) yea! and in addition...the problem is fixed with 8 gallons of 91 and some octane booster i think i just got some bad gas....and i dont mean the burrito kind.. |
Stick with NGK plugs and Shell or Chevron gasoline and you'll be just fine.
